I'm just putting this out there, so take it for what it's worth...
I don't like this Lean EFX / SX resurgence going on lately. I think it's foolish. Do what you will, folks, but if something goes wrong, who are you going to blame? Sure, if you've got SX, you know who to contact. But all we can say is that it was recalled, you were aware, and you chose to ignore it. For Lean EFX, is their contact info readily available? Have we ever met a rep from them, if they have them? Are they known for anything other than this knock-off product?
Russian Roullette, my friends, and it's one of the very very few games I'm not willing to play.
Carry on and be safe.
